When I am looking on any website such as Ebay, Asda etc and click on next page or view item unwanted pages are opening up sometimes 4 or 5 pages. Also I can not get rid of pop ups, I have disabled them, retarted Firefox updated everything and these problems are still an issue.

This problem has just started over the past week. When I need download a pdf file (such as tickets etc) it shows as 'Unknown size' so I cannot open it. The dowload list shows only downloads done months ago - although, up to last week, I had no problem. Cory MH replied earlier this week suggesting the following but I am not sure how to access the information. This is screen shot of the advice:

Can you check the properties of your places.sqlite file, which handles your bookmarks, browsing history, and downloads? It is contained in your Firefox profile folder, which you can access by going to the about:support page or:
• Help (or > ) > Troubleshooting Information
On that page, click the "Show Folder" button and that will open your profile folder in Windows Explorer. Look for the places.sqlite file and right click it. Select Properties and under the General tab, make sure that it isn't "Read-only".
You can also install the Places Maintenance extension to run maintenance on the file to see if that can fix it if it is corrupted. Please read the following articles first as they provide helpful hints and instructions that may be relevant to you:

I really need clarification as to where to find the 'about:support page' on Help/Troubleshooting etc.

This problem is a real nuisance as I will need to dowload boarding passes later in the week.

So I finally get a Surface Pro 3 and bring it home. Excited to install the "touch" version of Firefox, since I've used it on my non-touch computers for at least a decade, only to find that they've cancelled the development.

WTF?! Seriously? Worse is that I found the reason posted in a blog, "Not enough interest". Hmm, maybe it's because nobody knew about it? Even those that did, couldn't get it to work in the touch environment. Maybe it's because it wasn't released as a "release" and always as a Beta?

Here is a fact, you've lost this user for good. Development on this old version of non-touch is what you should stop on. I mean, what computers today AREN'T touch screen? If they're not, your current and even past versions are more than enough.

Firefox had a chance to gain some ground but that is now gone. Instead they've chosen to go with the smaller market Android, build their own OS (Good luck with that) and continue developing a "desktop" mode that is more than fine.

Instead they're leaving behind a market share that is larger than both Apple and Android COMBINED. Here's an idea - FIRE your management team 'cause they don't know crap about their users. If you ever release a version in the Windows Market, great. Until then, I'm gone and I'm sure I'm not alone.

Thanks but now I have to get this impossible to use desktop version off my Surface.

My printer menu opens in all my other program, including Chrome. My printer is operating. I've printed a page with it. Everything was fine until yesterday. I closed my system last night and rebooted this am. The problem still exists.

I didn't reset my Firefox printer settings because I don't want to create any other problems.

I am having problems with my computer, only two years old. Very slow, ran cleaner, AVG, and all looks ok, but it still slow. I downloaded firefox to see if it was Internet explorer, and it seemed to worsen the problem. My husband said I may be having problems with conflicting browsers, so I want to disable the firefox to see.

I know I can toggle the bookmarks on and off, but they should be there automatically, like they used to be. From other web sites I gather this is the way it is with a new version of Firefox that has come out. Everything worked fine before, why did you change it. This is not progress.

10/4/2014 Thank you Cor-el for your rapid response to my original question. I do believe I downloaded the Places Maintenance add on. But I have no idea as to how to access that add on and run it, if that's what I should do. I did try to restore a backed up HTML bookmark file. This seems to have changed the "wrong" URL that I get to a different wrong URL. Thanks.

Linux Mint 17. Firefox just installed from the repository. I have links to send news articles from various sources. I put in the addresses and the note in the box and when I click on Send nothing happens. I assumed it was something to do with my computer. I just tried sending the same article with Chrome. With Google Chrome it worked. I don't know if this is related but sometimes when a page is loading it hangs. After I hit the reload button it shows. The email link sending problem has shown many times before but I didn't think about trying a different browser before.

After I just sent a message in Google Chrome I tried it with Firefox and it worked. I did install the troubleshooter before I sent the message again.

I have recently started encountering problems when starting up firefox. the pages about:tabs and about:restore have ceased to exist. I currently get the error "the adress isnt valid" when typing it in manually.
